Managing agents, landlords, schools, care providers, businesses and homeowners in County Londonderry can all use one team for survey, supply, installation and evidence. We plan work around occupants and hand over a record for every door.
Where are FD30 doors used?
FD30 is the rating most buildings rely on. You will find it on flat entrance doors, doors onto escape corridors and stairs in houses in multiple occupation, kitchen doors in HMOs, and most internal doors on escape routes in offices, schools, surgeries and shops. Where smoke control matters too, the door is specified as FD30S (E30Sa), which adds a smoke seal and a tighter threshold.
The rating your building needs comes from its fire strategy or fire risk assessment, not from the door supplier. If you are unsure whether a door should be FD30 or FD60, we check the drawings, the risk assessment and what is installed now before we price anything. Our FD30 vs FD60 guide explains the difference.

Questions
Do you provide FD30 fire doors across County Londonderry?
Yes. We cover all of County Londonderry, including Derry and Coleraine. Surveys and written quotes are free.
Can a new FD30 door go into my old frame?
Sometimes. The frame has to be sound, square, securely fixed and compatible with the new leaf's certification. Many older frames are not, especially softwood linings or frames altered for previous doors. We check each frame on the survey and recommend a doorset only where the frame cannot be relied on.
How long does it take to fit an FD30 door?
A leaf into a sound frame is often a few hours. A full doorset including frame removal, fixing, sealing and making good is usually half a day to a day per opening, depending on access and the wall construction.
